Introduction

This library is an implementation of the JSON-LD specification in Python.

JSON, as specified in RFC4627, is a simple language for representing
objects on the Web. Linked Data is a way of describing content across
different documents or Web sites. Web resources are described using IRIs,
and typically are dereferencable entities that may be used to find more
information, creating a “Web of Knowledge”. JSON-LD is intended to be a
simple publishing method for expressing not only Linked Data in JSON, but
for adding semantics to existing JSON.

JSON-LD is designed as a light-weight syntax that can be used to express
Linked Data. It is primarily intended to be a way to express Linked Data in
Javascript and other Web-based programming environments. It is also useful
when building interoperable Web Services and when storing Linked Data in
JSON-based document storage engines. It is practical and designed to be as
simple as possible, utilizing the large number of JSON parsers and existing
code that is in use today. It is designed to be able to express key-value
pairs, RDF data, RDFa data, Microformats data, and Microdata. That is, it
supports every major Web-based structured data model in use today.

The syntax does not require many applications to change their JSON, but
easily add meaning by adding context in a way that is either in-band or
out-of-band. The syntax is designed to not disturb already deployed systems
running on JSON, but provide a smooth migration path from JSON to JSON with
added semantics. Finally, the format is intended to be fast to parse, fast
to generate, stream-based and document-based processing compatible, and
require a very small memory footprint in order to operate.
